Needs list:

  • Thatching machine or thatching rake
  • 1 pound of grass seed for every 250 sq ft
  • 10 pounds of 10-20-20 fertilizer for every 1000 sq ft

Optional:

    • Sprinkler with timer

When overseeding keep in mind that the new grass seeds are going to have to compete for water and nutrients with your existing grass.

For best results: thatch and then mow grass shorter than usual (do not bald existing lawn), spread grass seed and then a starter fertilizer with a spreader at rate indicated on packaging.

Because more seedlings fail during overseeding compared to planting a new lawn, you will get better results if you overseed twice. Spread the seed and fertilizer and water regularly, keeping the planted area moist but not wet.

Wait two weeks, mow at a high setting for longer grass blades and then overseed again. It is not necessary to fertilize a second time since the initial application will release nutrients over time. Keep planted area moist, but not wet.

Wait two more weeks, then mow at regular height and enjoy your restored lawn.
